GSS Audio Unveils Compact Subwoofer Driver Delivering Bass of Much Larger Units
GSS Audio demonstrated a new bass driver called the Model S1 at the High End Show in Vienna that measures just 62.5mm tall and operates in a 1.75-liter box while delivering bass equivalent to a subwoofer six times its size. The driver achieves this through extreme excursion capability (17mm in each direction) and an elaborate diaphragm design with ridges and spirals. The technology could enable space-efficient bass integration in soundbars, wall-mounted speakers, and compact home theater systems.
At the High End Show in Vienna 2026, audio component maker GSS Audio showcased the Model S1, a slim bass driver measuring 62.5mm tall and 299mm wide that can operate in a sealed box of just 1.75 liters. According to GSS Audio, the system can deliver bass equivalent to a subwoofer six times larger—roughly equivalent to an 8-inch or 10-inch subwoofer compressed into a box the size of a thick hardback book. The driver achieves this performance through exceptional excursion capability, with the diaphragm moving 17mm in each direction (34mm total), enabled by an elaborate design featuring ridges and spirals that manage surface area while maintaining consistent performance across the full movement range. GSS Audio has also optimized the magnet configuration and spider suspension system. In listening demonstrations, the compact system delivered controlled, powerful bass with notably clean deep sub-bass reproduction, performing well in near-field listening environments. The company is developing applications including soundbars with dual drivers and wall-mounted speakers with four drivers, positioning the technology as a solution for home theater and compact audio systems where space is limited.

GPT-5.5 Tops New AI Benchmark for Professional Workflows, Beating Claude Fable 5
OpenAI's GPT-5.5 achieved a 24.0% pass rate on the Agents' Last Exam (ALE), a new benchmark designed to measure AI performance on real-world professional tasks, narrowly beating Anthropic's Claude Fable 5 at 22.0%. The benchmark, developed by UC Berkeley researchers and 300+ domain experts, tests AI agents across 55 industries using authentic workflows from professional practitioners rather than isolated coding puzzles. The results highlight that current advanced AI models still fundamentally struggle with complex, long-horizon professional work despite recent progress.
Critical Infrastructure Protection Evolving Beyond Traditional Security as Drone Threats Multiply
Governments and security experts are grappling with how to protect critical infrastructure from drone threats, which can bypass traditional ground-based security measures. Recent conflicts have demonstrated that sensitive sites now face three-dimensional threats, prompting countries like China to tighten drone regulations and others to implement Remote ID mandates and geofencing. Experts argue that regulation alone is insufficient without detection capabilities and supply chain vetting to prevent circumvention of security frameworks.
